' IMPROVEMENT lN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 1323,7413, dated December 10, 1872.

To all whom it may concern:

Be it known that I, EDWARD BAYARD, of the city, county, and State of New York, have invented a certain new and useful Improvement in Method of and Apparatus for Generating Steam; and I hereby declare that the following is a description of the same, reference-being had to the accompanying drawing making a part of this specification, in which- Figure 1 is a plan view of the apparatus; Fig. 2 is a longitudinal section taken through the line 1 1" of Fig. 5; Fig. 3 is a transverse section, showing the interior of the apparatus;

Fig. 4 is a front elevation; and Fig. 5 is the rear-end elevation.

The same letters indicate like parts in the drawing.

I do not wish to be understood as limiting myself to the use of the boileror generator hereafter described, and as shown in the drawing, as my method of heating water is applicable to all. known forms of boilers, whether horizontalyvertical, or otherwise, in form or construction.

My method consists in burning gas or other volatile substances at or near the exterior of the vessel containing Water, and forcing the same, by a powerful blast, through a series of pipes into a central flue within the interior of the boiler, by whichan intense heat is obtained at a small expenditure of fuel in bulk as compared with the combustion of coal or wood to produce like results. Gas that will burn steadily under the action of a powerful blast of air will answer my purpose; but I find the best and most economical results are obtained by the use of gas made from crude petroleum by the apparatus of the Guaranty Gas-Ilight Company, patented by \Vren.

In Fig. 3' a central tube or flue, A, is shown within the shell of the boiler, with a tube, B,

on either side in the same plane of its axis,

riveted tothe same and extending outward f to and through the shell ofthe boiler, to

which the. other end is-in like manner secured. The tube 0 descends vertically from the under side of the flue A to the shell, and

is likewise secured at either end. These tubes, which form part of a series, are submerged belowthe Water in the boiler, as

shown by the water-level at D, the top por; tion of the flue A acting as a crown sheet. At the mouth of the tubes Bare shown the gas-pipes E, pointing into the tubes. On top of these tubes are shown the blast tubes or pipes F, also pointing into the tubes B. At the mouth of 'thevertical tube 0 the pipes E and F stand side by side vertically, pointing upward into the through themain G to the small pipes E, where it is ignited, while the blast passes through the main H and the small pipes F, uniting as and driving'witlr increasing force and increasing heat the combined flame through the tubes B and G into the central flue A, where the combustiofiis perfected without any residuum. At K, Fig. 5, is a register, placed in the rear end.of the center flue, which is opened when the. gas is ignited, and partially closed when the tube is heated. I place the air-pipes above the gas-pipes,as I find the blast to be more effective in striking the burning gas from that direction than from any other position, though I obtain good results by placing them under, on the sides, or through the gas-pipes.

v The improvement and advantage 0t my method of generating steam over any known process are so obviously plain that it may be superfluous to allude to them; yet I mention some inorder to more readily illustrate my ideas and what Iclai-m, viz: The strength of the boiler isincreased by the arrangement of the tubes, they acting as stays and braces; the absence of grate-bars, .fur'nace-doors, costly tire-bridges; flues, 850.; the cost of handling coal, and removal of cinders ashes avoided; chimneys and smoke-stacks are done away with; the tire is always under control, can be instantly applied and as quickly extinguished, and when lighted will generate steam in a few moments; the fuel,

being crude petroleum, or other volatile substances chea-ply converted into gas, and economically applied, as above.

What I claim, and desire to secure by Letters Patent, is-- I I 1. The gas and air-blast pipes G E and H F, arranged, substantially as described,-in combination with a boiler for generating steam, as herein specified.

2. The radial tubes 13 O O, in the .boiler, in combination with the gas and air-blast pipes G E and H F, substantially as and for the purpose herein specified.
